The RMC Ox-Yoke Shotgun Wonder Wads are pre-lubed with Wonder Lube 1000 Plus, take the place of the over powder card and cushion wad combination. They give a more dense shot pattern and increased range. No need for wet wad loading. By design, RMC Ox-Yoke has solved the problem of loading through a choked barrel. Wonder Wads have a memory and will return to their original size and shape after passing through the choke. A proper gas seal is maintained and will allow you the full benefits of your load. 100 per bag.
